An amebocyte or amoebocyte (/əˈmiː.bə.saɪt/) is a motile cell (moving like an amoeba) in the bodies of invertebrates including cnidaria, echinoderms, molluscs, tunicates, sponges, and some chelicerates. Moving by pseudopodia, amebocytes can manifest as blood cells or play a similar biological role.
Clockwise from top right: Amoeba proteus, Actinophrys sol, Acanthamoeba sp., Nuclearia thermophila., Euglypha acanthophora, neutrophil ingesting bacteria. An amoeba (/ ə ˈ m iː b ə /; less commonly spelled ameba or amœba; pl.: amoebas (less commonly, amebas) or amoebae (amebae) / ə ˈ m iː b i /), [1] often called an amoeboid, is a type of cell or unicellular organism with the ability ...
Pulmonary amoebiasis can occur from liver lesions by spread through the blood or by perforation of pleural cavity and lung. It can cause lung abscess, pulmono pleural fistula, empyema lung and broncho pleural fistula. It can also reach the brain through blood vessels and cause amoebic brain abscess and amoebic meningoencephalitis.
An amoeba of the genus Mayorella (Amoebozoa, Discosea). Amoebozoa is a large and diverse group, but certain features are common to many of its members. The amoebozoan cell is typically divided into a granular central mass, called endoplasm, and a clear outer layer, called ectoplasm.
From there, it can reach vital organs of the human body, usually the liver, but sometimes the lungs, brain, and spleen. [9] A common outcome of this invasion of tissues is a liver abscess, which can be fatal if untreated. [8] Ingested red blood cells are sometimes seen in the amoeba cell cytoplasm. [10]
Human microbiota are microorganisms (bacteria, viruses, fungi and archaea) found in a specific environment. They can be found in the stomach, intestines, skin, genitals and other parts of the body. [1] Various body parts have diverse microorganisms. Some microbes are specific to certain body parts and others are associated with many microbiomes.
Free-living amoebae (or "FLA") [1] are a group of protozoa that are important causes of infectious disease in humans and animals.. Naegleria fowleri is often included in the group "free-living amoebae", [2] [3] and this species causes a usually fatal condition traditionally called primary amoebic meningoencephalitis (PAM).
Entamoeba coli is a non-pathogenic species of Entamoeba that frequently exists as a commensal parasite in the human gastrointestinal tract. E. coli (not to be confused with the bacterium Escherichia coli) is important in medicine because it can be confused during microscopic examination of stained stool specimens with the pathogenic Entamoeba histolytica.
